Pneumatic flange gate valve

Yu valve manufacturer pneumatic gate valve Z641H, Z641W pneumatic cast steel gate valve, stainless steel pneumatic gate valve Pneumatic flange gate valve (Z641H, Z641W, Z641Y, pneumatic gate valve, pneumatic flange gate valve, pneumatic stainless steel gate valve, pneumatic cast steel gate valve, pneumatic carbon steel gate valve, chrome-molybdenum steel pneumatic gate valve, pneumatic hard seal gate valve, pneumatic hard seal elastic gate valve, pneumatic forged steel gate valve, stainless steel pneumatic gate valve, pneumatic high temperature gate valve, pneumatic explosion-proof gate valve): the most common open and close valve, Use the up and down work of the ram to connect (fully open) and cut off (fully close) the fluid medium in the pipeline. With reliable performance, convenient operation and maintenance, it has been widely used for controlling various media in petroleum, chemical, marine, and other departments.

Features of pneumatic flange gate valve:

1. Pneumatic gate valve is equipped with pneumatic actuator and manual mechanism;

2. The gate valve actuator adopts a double-cylinder structure. Compared with the single-cylinder pneumatic gate valve, its lifting force is doubled;

3. It solves the problem that some valve plates of single-cylinder pneumatic gate valve are wedged in the valve body and cannot be opened;

4. With a buffer mechanism, it can effectively reduce the wear of the valve plate sealing surface and valve body sealing surface caused by the downward impact of the piston when closing the valve, and at the same time, it can also avoid the jamming of the ram;

5. The fluid resistance is small, and the sealing surface is little scoured and eroded by the medium (the ram opening height is high)
